System and method for producing color shifting or gloss effect and recording medium with color shifting or gloss effect

ABSTRACT

A gloss effect image pattern is created on a recording medium having a first color by electronically creating a first electronic pattern ink, the first electronic pattern ink including a second color and including holes, the holes representing areas in the first electronic pattern ink wherein the second color is absent; electronically creating an electronic image region having a pattern; electronically painting, using the first electronic pattern ink, a background of electronic image region and the pattern of the electronic image region; electronically painting a predetermined portion of the holes within the electronic image region with a third color, the third color matching the first color of the recording medium; and rendering, using marking materials, the electronic image region on the recording medium.

BACKGROUND

In conventional printing processes, requiring security measures, apattern color space having specialty imaging characteristics have beenutilized to provide the security measures and prevent counterfeiting ofprinted materials.

In addition, in conventional printing processes, a pattern color spacehas been utilized, in part on variable data, such as printing logos,serial numbers, seat locations, or other types of unique identifyinginformation on printed materials.

In security applications, it is desirable to add information to adocument that prevents or hinders alterations and counterfeiting. Thesesecurity elements may conflict with the overall aesthetics of thedocument.

Specialty imaging has been used, conventionally, in printed materials toprovide fraud protection and anti-counterfeiting measures. Some examplesare in prescriptions, contracts, documents, coupons, and tickets.Typically, several specialty imaging techniques are used at variouspositions in a document. However, specialty imaging text techniques takeup space in the document.

One example of a conventional specialty imaging technique restrictsdesigners to use rectangular areas for security elements of documents.This may be acceptable for locating security elements in headers,footers, or similar areas of documents. However, rectangular securityelements may not be as “pleasing” in other document areas.

With reference to FIGS. 1 and 2, typical specialty imaging techniquesare implemented in document security elements that are restricted torectangular areas. This is an example of current specialty imagingcapabilities which provide static (i.e., non-dynamic) specialty imagingmarks with respect to “design” freedom.

In FIG. 1, the rectangular footer provides a logo which incorporates aGlossMark™ text in the right of the rectangular area. Also, microtextlines, another type of a rectangular element, are included as part ofthe table delineation in FIG. 1.

In FIG. 2, GlossMark™ text is used in the rectangular area at thebottom, a Fluorescent text is used in the rectangular area in the topleft, and a microtext line is in the center left portion of a parkingpermit. These elements are useful in the context of security, but lackaesthetic value.

In one conventional specialty imaging technique, the method includesdefining a variable portion of the pattern color space in a pagedescription language; defining a fixed portion of the pattern colorspace in the page description language; defining a bounding shape forthe pattern color space in the page description language; and defining aprocedure for painting the variable and fixed portions within thebounding shape in the page description language.

In this conventional specialty imaging technique, the variable portionof the pattern color space is based at least in part on variable dataassociated with the print job and at least one object within the printjob identifies the pattern color space for a color parameter.

In another conventional security printing technique, the method includesthe use of color shifting ink, which appears as one color from a certainangle and another color from another angle. In other words a special inkis required to realize the color shift effect.

For example, a printed security feature for printed currency utilizescolor-shifting ink to print the numerals located in the corners on thefront of the bill. More specifically, on a US $100 banknote, the greencolor use to print the denomination in the corners on the front of thebill will “shift” to grey and back to green as the bill is tilted backand forth to change the viewing angle.

The “optically variable ink” is not widely commercially available andcannot be replicated by any copiers, which only “see” and replicatepatterns from a fixed angle.

Therefore, it is desirable to provide a specialty imaging technique,utilizing color-shifting, which does not require special inks or markingmaterials, and still cannot be readily replicated by conventionalcopiers and/or scanner.

In addition, it is desirable to provide a specialty imaging techniquethat is applicable to Variable-Data Intelligent PostScript™ Printwareworkflows and that transmit an image a single time and subsequently onlysubmit the variable text string to the digital front end.

DETAILED DESCRIPTION

For a general understanding, reference is made to the drawings. In thedrawings, like references have been used throughout to designateidentical or equivalent elements. It is also noted that the drawings maynot have been drawn to scale and that certain regions may have beenpurposely drawn disproportionately so that the features and concepts maybe properly illustrated.

The term “data” refers herein to physical signals that indicate orinclude information. An “image,” as a pattern of physical light or acollection of data representing said physical light, may includecharacters, words, and text as well as other features such as graphics.

A “digital image” is by extension an image represented by a collectionof digital data. An image may be divided into “segments,” each of whichis itself an image. A segment of an image may be of any size up to andincluding the whole image.

The term “image object” or “object” as used herein is believed to beconsidered in the art generally equivalent to the term “segment” andwill be employed herein interchangeably.

In a digital image composed of data representing physical light, eachelement of data may be called a “pixel,” which is common usage in theart and refers to a picture element. Each pixel has a location andvalue. Each pixel value is a bit in a “binary form” of an image, a grayscale value in a “gray scale form” of an image, or a set of color spacecoordinates in a “color coordinate form” of an image, the binary form,gray scale form, and color coordinate form each being a two-dimensionalarray defining an image.

An operation performs “image processing” when it operates on an item ofdata that relates to part of an image.

“Contrast” is used to denote the visual difference between items, datapoints, and the like. It can be measured as a color difference or as aluminance difference or both.

A digital color printing system is an apparatus arrangement suited toaccepting image data and rendering that image data upon a substrate.

The “RGB color model” is an additive color model in which red, green,and blue light are added together in various ways to reproduce a broadarray of colors. The name of the model comes from the initials of thethree additive primary colors, red, green, and blue. The main purpose ofthe RGB color model is for the sensing, representation, and display ofimages in electronic systems. RGB is a device-dependent color model:different devices detect or reproduce a given RGB value differently,since the color elements and their response to the individual R, G, andB levels vary from manufacturer to manufacturer, or even in the samedevice over time. Thus, an RGB value does not define the same coloracross devices without some kind of color management.

The “CMYK color model” is a subtractive color model, used in colorprinting, and is also used to describe the printing process itself. CMYKrefers to the four inks used in some color printing: cyan, magenta,yellow, and black.

“Colorant” refers to one of the fundamental subtractive C, M, Y, K,primaries, which may be realized in formulation as, liquid ink, solidink, dye, or electrostatographic toner. A “colorant mixture” is aparticular combination of C, M, Y, K colorants.

An “infrared mark” is a watermark embedded in the image that has theproperty of being relatively indecipherable under normal light, and yetdecipherable under infrared illumination by appropriate infrared sensingdevices, such as infrared cameras.

“Metameric” rendering/printing is the ability to use multiple colorantcombinations to render a single visual color, as can be achieved whenprinting with more than three colorants.

With reference to FIG. 3, a printing system (or image rendering system)100 suitable for implementing various aspects of the exemplaryembodiments described herein is illustrated.

The word “printer” and the term “printing system” as used hereinencompass any apparatus and/or system; such as a digital copier,xerographic and reprographic printing systems, bookmaking machine,facsimile machine, multi-function machine, ink-jet machine, continuousfeed, sheet-fed printing device, etc.; which may contain a printcontroller and a print engine and which may perform a print outputtingfunction for any purpose.

The printing system 100 generally includes a user interface 110, adigital front end controller 120, and at least one print engine 130. Theprint engine 130 has access to print media 135 of various sizes and costfor a print job.

A “print job” or “document” is normally a set of related sheets, usuallyone or more collated copy sets copied from a set of original print jobsheets or electronic document page images, from a particular user, orotherwise related. For submission of a regular print job (or customerjob), digital data is generally sent to the printing system 100.

A sorter 140 operates after a job is printed by the print engine 130 tomanage arrangement of the hard copy output, including cutting functions.A user can access and operate the printing system 100 using the userinterface 110 or via a workstation 150. The workstation 150 communicateswith the printing system 100 via a communications network 160.

A user profile, a work product for printing, a media library, andvarious print job parameters can be stored in a database or memory 170accessible by the workstation 150 or the printing system 100 via thenetwork 160, or such data can be directly accessed via the printingsystem 100. One or more color sensors (not shown) may be embedded in theprinter paper path, as known in the art.

With respect to FIG. 4, an exemplary digital front end controller 200 isshown in greater detail. The digital front end 200 includes one or moreprocessors, such as processor 206 capable of executing machineexecutable program instructions.

In the embodiment shown, the processor is in communication with a bus202 (e.g., a backplane interface bus, cross-over bar, or data network).The digital front end 200 also includes a main memory 204 that is usedto store machine readable instructions. The main memory also beingcapable of storing data. Main memory may alternatively include randomaccess memory (RAM) to support reprogramming and flexible data storage.Buffer 266 is used to temporarily store data for access by theprocessor. Program memory 264 includes, for example, executable programsthat implement the embodiments of the methods described herein. Theprogram memory 264 stores at least a subset of the data contained in thebuffer.

The digital front end 200 includes a display interface 208 that forwardsdata from communication bus 202 (or from a frame buffer not shown) to adisplay 210. The digital front end 200 also includes a secondary memory212 includes, for example, a hard disk drive 214 and/or a removablestorage drive 216, which reads and writes to removable storage 218, suchas a floppy disk, magnetic tape, optical disk, etc., that storescomputer software and/or data.

The secondary memory 212 alternatively includes other similar mechanismsfor allowing computer programs or other instructions to be loaded intothe computer system. Such mechanisms include, for example, a removablestorage unit 222 adapted to exchange data through interface 220.Examples of such mechanisms include a program cartridge and cartridgeinterface (such as that found in video game devices), a removable memorychip (such as an EPROM, or PROM) and associated socket, and otherremovable units and interfaces which allow software and data to betransferred.

The digital front end 200 includes a communications interface 224, whichacts as both an input and an output to allow software and data to betransferred between the digital front end 200 and external devices.Examples of a communications interface include a modem, a networkinterface (such as an Ethernet card), a communications port, a PCMCIAslot and card, etc.

Computer programs (also called computer control logic) may be stored inmain memory 204 and/or secondary memory 212. Computer programs may alsobe received via a communications interface 224. Such computer programs,when executed, enable the computer system to perform the features andcapabilities provided herein. Software and data transferred via thecommunications interface can be in the form of signals which may be, forexample, electronic, electromagnetic, optical, or other signals capableof being received by a communications interface. These signals areprovided to a communications interface via a communications path (i.e.,channel) which carries signals and may be implemented using wire, cable,fiber optic, phone line, cellular link, RF, or other communicationschannels.

Part of the data generally stored in secondary memory 212 for accessduring digital front end operation is a set of translation tables thatconvert an incoming color signal into a physical machine signal.

This color signal can be expressed either as a colorimetric value;usually three components as L*a*b*, RGB, XYZ, etc.; into physicalexposure signals for the four toners cyan, magenta, yellow and black.These tables are commonly created outside of the digital front end anddownloaded, but are optionally created inside the digital front end in aso-called characterization step.

In the some of the descriptions below, specialty imaging elements areused in a dynamic pattern generation process to provide securityfeatures.

For example, a specialty imaging technique, as illustrated in FIGS. 5-8,create a pattern color space that incorporates specialty imagingfeatures using standard page description language constructs, such asPostScript™ constructs. The pattern color space can be selected as acolor for a color parameter for an object (e.g., lines, text, geometricshapes, freeform shapes, etc.) or an object characteristic (e.g., linecolor, fill color, foreground color, background color, etc.) in thedocument.

Specialty imaging techniques can be implemented by creating a specialtyimage object. Alternatively, specialty imaging techniques can beimplemented using page description language constructs, such asPostScript™ constructs, to create a pattern color space, sometimesreferred to as a “pattern ink.” In other words, within page descriptionlanguages, specialty imaging text and specialty imaging pattern inks canbe implemented.

Rather than defining the specific string to be rendered at a specifiedlocation on the page, a specialty imaging string may be used to define adynamically created pattern ink. This pattern ink is subsequentlyaccessible by other page description language drawing and renderingcommands through selection as a color parameter in the command.

With reference to FIG. 5, an exemplary graphic illustrates an exemplaryembodiment of a process for dynamic creation of pattern inks. Throughspecialty imaging, the shirt, as well as the cart and the rails, can bechanged into security elements on a variable data basis.

In this example, a “tile” of GlossMark™ text is defined as a patternink. This pattern ink can be previously designed with staticcharacteristics. Alternatively, the pattern ink may be dynamicallydesigned in conjunction with the processing of a corresponding printjob. Both previously and dynamically-designed pattern inks can alsoincorporate variable data associated with the print job, as illustratedby the string “shirt” for the shirt (see FIG. 7) and “cart” for the cart(see FIG. 8). Additionally, the rails are rendered using a microtextstring (see FIG. 8).

An exemplary embodiment of a pattern ink that includes a specialtyimaging GlossMark™ test effect for the string “XEROX!”™ may be createdusing the following exemplary PostSript™ pseudo-code:

  TABLE-US-00001 /GlossFont /NeueClassic-GL-24 def /GlossFontsize 28.8def /GlossFontstring (XEROX!) def %% this sets the Font parameters. /PatternType 1 %% tiling properties can be defined similar to Holladaydots  /BBox [0 0 GlossFontstring stringwidth pop GlossFontsize]  /XStepGlossFontstring stringwidth pop  /YStep smallfontsize %% geometricvalues for the tiling rectangle  /PaintProc { 0 0 moveto GlossFontstringshow  } %% this creates the variable data string defined throughGlossFontstring matrix makepattern /GlossTextPaint exch def %%identifying the patterns as GlossTextPaint

FIG. 6 shows the exemplary pattern ink (or pattern color space) createdby the PostSript™ pseudo-code listed above. The string “XEROX!”™ can betraced as the texture change of the halftone for this pattern ink. Inthis example, the pattern color space of FIG. 6 is available as a“color” or “ink” selection for subsequent PostScript™ drawing commands.Note that the geometry and size of the pattern in FIG. 6 may becharacterized as a fixed portion of the pattern ink. In the exampleabove, the geometry and size of the pattern is created in the first stepof the pseudo code.

In one embodiment, a pattern ink (or pattern color space) used fortiling is defined with respect to an origin of a page (i.e., the patternink is available for all objects on the page, except for image objects)and not with respect to a specific object.

For example, this means that the GlossMark™ text inside the shirt maystart with the letter “X” or any other letter of the string depending onthe location of the object in relation to the page. In other words, twoidentical shirts, drawn at different locations on the page may havedifferent internal GlossMark™ patterns, since their starting positionvaries.

With reference to FIG. 7, the pattern ink of FIG. 6 is used as the fillcolor for the shirt of FIG. 5 using the word “shirt” as the variabledata string (rather than “Xerox!”)™. In other words, the word “shirt” isused as GlossMark™ text to create the pattern ink used to render theshirt area of FIG. 5. The word “shirt” is tiled with respect to otheroccurrences of the word which is based on the tile size for the patternink.

Multiple pattern inks can be defined. For example, a pattern consistingof lines of microtext may be defined and used to render the rails at thebottom of the graphic. FIG. 8 provides an enlargement of a small area ofthe rails to show this pattern ink with microtext.

As previously noted, specialty imaging techniques may be text based,wherein text is any symbol that is encapsulated as font, or image based.In the conventional specialty imaging techniques, the text basedspecialty imaging techniques can be realized in real-time, whereas theimage-based conventional specialty imaging techniques are performed asan offline process, eliminating any real-time capabilities, because ofthe computational requirement for images that cannot easily be doneinside a Postscript™ dataflow through a digital front end.

In the conventional specialty imaging techniques, pattern inks in pagedescription languages; such as PostScript™ and PDF (Portable DocumentFormat); are typically used for repeating patterns, essentially, thepattern inks correspond to tiles that are regularly laid across thepage.

In a typical situation, each pattern ink is a rectangular area that isrepeated in both x-direction and y-direction across the page. SubsequentPostScript™ commands ‘expose’ that pattern to the printed page in thedesired spots, where the phasing of the pattern ink is constant withrespect to the original definition.

For example, by defining two pattern inks that have the same averagevisual color (say in Lab space) but very distinct toner combinations,variable data (text-based) UV fluorescence specialty imaging can berealized.

In this example, the background is ‘painted’ with one of the patterninks and the foreground with the other, resulting in a distinct UVfluorescence. In essence, the components of the specialty imaging effectare loaded into distinct pattern inks and subsequently selectively‘paint’ with these two components.

For an image-based real-time specialty imaging technique, the approachdescribed above needs to be inverted. In other words, the image isloaded into the pattern ink memory. This leads to a single pattern ink.

More specifically, the image based real-time specialty imaging techniqueuses a specialty imaging font (such as a GlossMark™ font orCorrelationMark™ font) in conjunction with the variable data string anduses the image as the “paint” that is poured through the specialtyimaging font.

It is noted that the various features of the process disclosed hereinmay be implemented using hardware, software, or firmware in any suitablecombination.

The image based real-time specialty imaging technique process forprocessing a print job begins when the print job, including variabledata to be used in conjunction therewith, in a page description languageis received at a digital front end associated with a printing system. Atleast one object within the print job includes a specialty imaging font(such as a GlossMark™ font or CorrelationMark™ font) that provides fraudprotection for printed materials resulting from the print job.

A pattern color space is created using the actual image of the print jobso that such that the specialty imaging font (such as a GlossMark™ fontor CorrelationMark™ font) is painted with the pattern color space in atiling manner. In other words, a data string is created using thespecialty imaging font (such as a GlossMark™ font or CorrelationMark™font) and the specialty imaging font data string is painted with theactual image of the print job.

The image based real-time specialty imaging technique process forprocessing a print job creates a GlossMark™ or CorrelationMark™, inreal-time, by: defining, in the page description language, a variableportion; defining, in the page description language, a fixed portion ofthe pattern color space.

The fixed portion is the image of the print job; defining, in the pagedescription language, a bounding shape for the pattern color space; anddefining, in the page description language, a procedure for painting thevariable and fixed portions within the bounding shape, with the image ofthe print job. The variable portion may be based in part on variabledata associated with the print job. The fixed portion (“paint”) is theimage of the print job.

The variable data string that is created using the specialty imagingfont (such as a GlossMark™ font or CorrelationMark™ font) is paintedwith the image of the print job, wherein specialty imaging effects inthe specialty imaging font is used to create the GlossMark™ orCorrelationMark™, with the image being used as the paint, instead ofusing two different pattern inks to create the GlossMark™ orCorrelationMark™.

In implementing the image based real-time specialty imaging techniqueand creating a variable data string, the process does not know, inadvance, what the string is going to be used. Additionally, if the sizeof the font (in pixels) is compared with the size of the image, theselected image is not typically exactly N-lines high and M-characterswide.

In order to circumvent this situation, a single pattern ink cell whitespace is created on the top and side of the pattern cell, as illustratedin FIG. 9. Preferably, the single pattern ink cell white space iscreated only once and is placed in a pattern cache for performance.

It is noted that it is not important on which sides the white space iscreated as long as it is created in both the vertical and horizontaldirection since the “pattern” of FIG. 9 is tiled across the entire page,and thus, the white space will be all around the image.

The required size of the white space can be calculated from thespecialty imaging font's properties. With respect to the verticaldirection (320 of FIG. 9) the line-height of the specialty imaging fontis utilized as the height 320 of the white space. Through the tiling,the image based real-time specialty imaging technique will create a fullline of white space above and below the image.

When writing the variable data string with the effect, the ceiling{imageheight/lineheight} is the number of lines of variable data text.If the variable data text string does not extend across this range, theimage based real-time specialty imaging technique can (a) fill theremainder with a blank “ ” character or preferably (b) replicate thestring.

The horizontal white space (310) can be determined by two differentscenarios.

In the first scenario, the image based real-time specialty imagingtechnique deals with strings that physically fit into image size. Anupper bound to the white space would be the image width parameter.

It is noted that the upper bound could be extended by the known stringlength limitations [variable data field length association].

In a second scenario, the image based real-time specialty imagingtechnique adds additional white space to the side of the image(essentially the remainder of the page). This is utilized when theexpected string is completely unknown.

Once the pattern ink (FIG. 9) is created, the pattern ink is now used asa “paintbrush” to actually render the variable data text. In contrast toall previous specialty imaging approaches, the image based real-timespecialty imaging technique uses the specialty imaging effect embeddedin the delivered fonts and use the pattern ink (FIG. 9) as the“constant” part of the method.

An exemplary embodiment of specialty imaging effects in the specialtyimaging font being used to create the GlossMark™ or CorrelationMark™,with the image being used as the paint, may be created using thefollowing exemplary

Variable or personalized data is then written using the pattern inkusing CorrelationMark™ or GlossMark™ fonts. FIG. 10 shows a ‘typical’GlossMark™ font element (in this case the letter “A” (410)).

FIGS. 11 and 12 show magnified portions (500 and 600) of aCorrleationMark™ and GlossMark™ string (XEROX)™, respectively, printedusing the same image as the pattern ink (FIG. 9). The internalstructure, that the specialty imaging effect and the text havemaintained, is clearly visible.

More specifically, in FIG. 11, the dotted box 510 encloses the letter X(which has been traced 515) of the CorrleationMark™ string (XEROX)™. Inaddition, in FIG. 12, the dotted box 610 encloses the letter X (whichhas been traced 615) of the GlossMark™ string (XEROX)™.

It is noted, from FIGS. 11 and 12, that the available dynamic range ofthe image is lost since all areas have maintained a certain percentageof “white space” for the specialty imaging effect.

Moreover, it is noted that the images turn ‘lighter’ than the imagewould have been printed in the normal path due to the additional whitespace. However, the darkness adjustment can be performed in an offlinestep. In addition, the darkness can be approximately adjustment by usinga simple data scale inside the PostScript™ data.

An example of providing specialty marks is the use of color shiftingink, which appears as one color from a certain angle and another colorfrom another angle. Conventionally, color shifting required a specialink or marking material.

To avoid the use of special inks or marking materials, the colorshifting result may be realized by creating a pattern of two differentcolors, wherein each color has a different height and at least one ofthe colors is created with a very thin line; for example, one pixelwidth line.

It is noted, as illustrated in FIG. 13, that there is color shift with710/720 and 730/720, but not if just 710/730. The intersection of710/730 creates the distinct line which virtually disappears whenshifting.

For example, as illustrated in FIG. 13, a color shifting image 700 canbe created using two colors 710 and 730. Each of the colors 710 and 730has a marking material height, H1. The color shifting image 700 furtherincludes a third color 720 which has a marking material height, H2,wherein the marking material height, H2, is greater than the markingmaterial height, H1.

In one example, the two colors 710 and 730 may be cyan (C) and magenta(M), while the third color 720 may be a composite black such that thecolor 720 is composed of 100% black (K) and 50% of cyan (C), magenta(M), and yellow (Y). The composite black (third color 720) would havemarking material height, H2, which is 2.5 times greater than the markingmaterial height, H1.

It is noted that in the example of FIG. 13, the high color black 720 iswider than the low colors 710 and 730 (cyan and magenta). The smallestmagenta or cyan square may be one pixel.

It is further noted that the reverse, where the low color is wider thanthe high color does not result in a color shift.

It is noted that the color shift may go from black and magenta to black,whereas conventional US currency goes from gold to green.

It is also noted that the low color may be created using a single colorcomponent marking material; a single color marking material may be cyancolored marking material (toner), magenta colored marking material(toner), or yellow colored marking material (toner). When the low coloris created using a single color component marking material, thebackground of the color shifting region may be initially rendered withthe single color component marking material associated with the lowcolor. Thereafter, the high color can be rendered, in the color shiftingregion, over the rendered background so as to create the markingmaterial height difference between the low color and the high color.

If the low color is created using more than one single color componentmarking material, the background of the color shifting region may beinitially rendered with the single color component marking materialsassociated with the low color. Thereafter, the high color can berendered, in the color shifting region, over the rendered background soas to create the marking material height difference between the lowcolor and the high color.

As noted above, in the area of security printing, documents areprotected from copying, forging, and counterfeiting using multipletechniques. Specialty Imaging is one such method of security printingwhich uses standard materials, such as papers, inks, and/or toners.

MicroGloss (or Artistic Black for VIPP) is a Specialty Imagingtechnique, which does not require a special tool; e.g., UV light to viewand is especially strong in anti-copying.

MicroGloss uses a pair of colors which appear about the same whenviewing straight on but show a differential gloss when the image istilted due to the pile height of the toner or ink.

MicroGloss can also be used to create two micro gloss layers such thatonly the first micro gloss layer is visible when viewing the imagestraight on, and the second micro gloss layer is viewable upon tiltingthe image. It is noted that upon tilting the image the first micro glosslayer is no longer visible.

To create a two layered micro gloss image, one pattern ink with aMicroGloss color pair and variable data is created, and then a secondpattern ink with a visibly different MicroGloss color pair but the samevariable data is created.

The background of the image is written with the first pattern inkfollowed by the second layer with the second pattern ink and differentvariable data.

As illustrated in FIG. 14, the first ink pattern may be composedColor1-High 800 (such as black hi) and Color1-Low 810 (such as blacklow) with variable data “SAMPLE.”

As illustrated in FIG. 14, the second ink pattern may be composed ofColor2-High (such as brown high) and Color2-Low (such as brown low) withvariable data “SAMPLE.” The second ink pattern is used to paint variabledata “MICRO.”

Upon rendering this image, the variable data “SAMPLE” is rendered inColor1-Low 810 and the background is rendered in Color1-High 800;however, where the portions of the variable data “MICRO” overlap thevariable data “SAMPLE,” the overlapping portions (within ovals 830) arerendered with Color2-Low, and where the portions of the variable data“MICRO” overlap the background, the overlapping portions (within ovals840) are rendered with Color2-Hi.

In the example discussed above, the rendered image would include a blackhi background with black low “SAMPLE.” The rendered image would alsoinclude brown low portions (within ovals 830) where portions of thevariable data “MICRO” overlap the variable data “SAMPLE,” and brown hiportions (within ovals 840) where the portions of the variable data“MICRO” overlap the background.

It is noted that hi/low color pair may be dark red or any of the hi/lowcolor pairs identified in co-pending U.S. patent application Ser. No.13/776,868, filed on Feb. 26, 2013. The entire content of co-pendingU.S. patent application Ser. No. 13/776,868 is hereby incorporated byreference.

It is also noted that gloss marks are not scalable because gloss marksrequire a new font for each font size. Moreover, MicroGloss only worksat small sizes.

Thus, it is desirable to realize a scalable gloss effect.

Such a scalable gloss effect can be realized by rendering one regionwith a relatively smooth surface while rendering another region with arelatively rougher surface. The appearances of the two surfaces areapproximately the same at one angle, while giving a gloss effect; e.g.,text or graphics; at another angle.

Gloss marks, as shown in FIG. 15, create a gloss effect by using twodifferent halftone patterns 910 and 920. As illustrated in FIG. 15, thebackground is rendered using a first halftone pattern 910 and the letterH is rendered using a second halftone pattern 920. To a casual observer,the image 900 will appear as one color and pattern at one angle, whilethe character “H” can be seen when tilted. In other words, the H appearsto the causal observer as being drawn into the image when the image istilted.

MicroGloss, as illustrated in FIG. 16, creates a gloss effect by usingtwo different ink or toner pile heights. To a casual observer the image950 will appear as one color 960 at one angle, while the gloss character970 can be seen when tilted.

As illustrated in FIG. 17, a gloss effect is created by using twodifferent patterns with one pattern being relatively smoother than theother pattern. In FIG. 17, the “H” is smoother as compared to thebackground.

In addition, as illustrated in FIG. 17, the “H” has yellow color holes(1010) and compared to no color (white) holes (1020) in the background.It is noted that clear toner would be used in place of yellow ifavailable.

To a casual observer the image 1000 will appear as one color and patternat one angle, while the character “H” can be seen when tilted. It isnoted that this gloss effect is scalable.

To create the gloss effect of FIG. 17, one pattern ink is created withwhite holes and a second pattern ink is created with yellow holes.Thereafter, a text box is created with a certain background color (suchas magenta) and white holes (1020) are added. The letter, “H,” is thenwritten and yellow dots (1010) are added.

As illustrated in FIG. 18, a reverse gloss effect is created by usingtwo different patterns with one pattern being relatively smoother thanthe other pattern. In FIG. 18, the background is smoother as compared tothe “H.”

In addition, as illustrated in FIG. 18, the “H” has white color holes(1110) and compared to yellow holes (1120) in the background. It isnoted that clear toner would be used in place of yellow if available.

To create the gloss effect of FIG. 18, one pattern ink is created withwhite holes and a second pattern ink is created with yellow holes.Thereafter, a text box is created with a certain background color (suchas magenta) and yellow holes (1220) are added. The letter, “H,” is thenwritten and white dots (1110) are added.

It is noted that a better color match can be realized by adding darkerpixels 1230, as illustrated in FIG. 19. In FIG. 19, the “H” has yellowcolor holes (1210) and compared to no color (white) holes (1220) in thebackground, as well as, darker pixels 1230 in the background.

Specialty Imaging techniques often rely on creating metameric patternink pairs such as UV (ultraviolet)/florescence and IR (infrared). Thescalable gloss effect, described above, used a pair of pattern inks thatappear about the same at one angle and show a differential gloss effectwhen tilted.

It is noted that Specialty Imaging quality is judged on the strength ofthe effect; e.g., UV signal and the hiding between the foreground andbackground pattern inks. In other words, the test is whether the signal(pattern) that is seen under UV illumination can be seen under ambientillumination. Conventionally, distraction patterns, color compensation,and/or noise have been used to help in hiding, but at the cost of effect(signal) degradation.

As illustrated in FIG. 20, an example of an UV (ultraviolet)/florescenceeffect is created by adding both a structure and color to enhance thehiding between the foreground and background pattern inks.

In this example, as illustrated in FIG. 20, the structure in the tophalf (1310) of the image 1300 is a triangle 1330. The triangle structure1330 is in both the foreground and the background.

The background pattern ink colors may be cyan, magenta, and yellow whilethe foreground pattern ink colors may be red, blue, white, yellow, andmagenta.

As illustrated in FIG. 20, the top half (1310) of the image 1300includes the string Xerox™.

The structure in the bottom half (1320) of the image 1300 is a diamond1350 and a small square 1360 at its center. The diamond 1350 and smallsquare 1360 structure is in both the foreground and the background.

As illustrated in FIG. 20, the bottom half (1320) of the image 1300includes the string Xerox™.

To enhance Specialty Imaging quality, color substrates are used inconjunction with Specialty Imaging color matching techniques, wherein atleast one of the pattern inks has holes allowing the substrate color toshow through.

To enhance quality, the substrate color that shows is matched in theother pattern ink by reproducing the same color via available markers,thereby realizing improved color matching (or better hiding) between theforeground and background pattern inks with little or no degradation ineffect.

As noted above, to enhance quality, the substrate color that shows ismatched in the other pattern ink by reproducing the same color viaavailable markers.

In realizing this enhancement, as illustrated in FIG. 21, one patternink allows the color of the substrate 1400 to be viewed via holes 1450in the pattern ink 1425. The other pattern ink, as illustrated in FIG.22, fills these holes with the matching color marker 1475

The pattern inks appear almost identical in color but exhibitdifferential properties in other areas, such as gloss effect.

This allows improved color consistency between the foreground andbackground pattern inks currently used in UV/florescence, IR, and glosseffects.

FIGS. 21 and 22 demonstrate the use of a colored substrate 1400 with asame color marker 1475.

FIG. 21 shows a colored (color1) substrate 1400 with black markers 1425on both sides and no marker in the center (hole 1450). This examplepattern ink shows colors black/color1/black, wherein color1 is from thesubstrate.

FIG. 22 appears the same color as FIG. 21, but has a difference in thatcolor1 is from a marker. This difference can be used to create securityelements such as UV markers.

In the cases where the substrate does not match a primary marker colorin the printer, the appropriate mix of marker materials filling theholes can be used to achieve color consistency.

It is further noted that a comparison of images using holes showingyellow substrate and holes filled with yellow marker verses using holesshowing white substrate and holes filled with yellow ink, the glosseffect works in all cases.

However, the color matching is improved when the holes are filled with amarking material, preferably a marking material matching the color ofthe substrate, by making it more difficult to read the text when thesubstrate is not tilted.

In summary, the use of a color substrate and matching color markerenhances Specialty Imaging quality. The color of the substrate showsthrough holes in one pattern ink, while the corresponding holes inanother pattern ink are filled with a color marker matching the color ofthe substrate.

The differential properties between the filled and unfilled holes areused to create Specialty Imaging effects such as gloss and UV.

More specifically, if the holes are filled with a marking materialhaving a color matching the color of the substrate upon which the imageis being rendered, a gloss effect is realized.

If the holes are filled with a marking material having a color matchingthe color of the substrate upon which the image is being rendered, a UVeffect is realized by the fluorescents in the recording medium orsubstrate showing through the holes.

It is further noted that a copier or scanner also views the substratecolor and marker filled holes the same for superior anti-copyproperties.

For example, if the image illustrated in FIG. 18 was rendered on asubstrate having a color matching the color of the marking materialassociated with holes 1120, a copier or scanner would view the imageillustrated in FIG. 18 as a solid color, not discerning the “H.”
